Improved chair



UNITED STATES PATENT OFFICE.

HENDERSON WILLARD, OF GRAND RAPIDS, MICHIGAN.

IMPROVED CHAIR.

Specification forming part of Letters Patent No. 101,957, dated April 12, 1870.

To all whom 'tt may concern:

Be it known that I, HENDERSON WILLAED, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Chairs 5 and I do hereby declare the following to be a full and sufficient descriptionl of the same, reference being had to the accompanying drawings, which make part of this specicaton, in which- Figure l is a perspective view of a cylinder of wood, showing the method of cutting the chairs. Fig. 2 is a similar view of a complete chair. Fig. 3 is a central vertical section of the same, and Fig. 4 is a perspective view of the improved chair-seat.

Like letters of reference indicate like parts in the several figures.

The nature of my invention consists in cutting from a complete cylinder of wood chairs which, when provided with a seat, are as strong as any common chair now in use.

It also consists in a peculiar and novel springseat, being a spiral coil of wood of suflicient thickness.

In the drawings, A may represent a. cylinder of wood of proper size, and cut out from a solid piece of timber in any suitable known manner.

I prefer making the cylinder the length of two chairs, as I can save material in the manufacture of chairs in that way.

A cut, ct, Fig. l, is made, which forms the backs of two chairs.

Cuts b, Fig. 1, take away pieces which leave legs c.

A suitable hoop, d, Fig. 3, is then fastened tothe inside of the chair, to form a bearing for the seat e.

This seat e (shown in Fig. 4) is constructed of a spiral coil of a strip of wood, either cut out by a band-saw, or else prepared in any other suitable manner. This coil, resting with its outside rim on the hoop d, forms a perfect spring-seat.

The wh ole chair may be varnished or painted to present a very pleasing appearance.

B y cutting out two chairs at a time from one length ot' cylinder made for that purpose, a great saving of timber is made, no pieces being lost except those out away by cuts b, to form the legs of the chair.

Of course, any kind of seat can be used with this chair, and I do not wish to be understood as confining myself to the one described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A chair cut from a complete cylinder of wood, substantially in the manner herein described. A

2. A spring-seat consisting of a spirallycoiled strip of wood, substantially as described.

HENDERSON WILLARD.
